The setting of the guide rod 304 improves the sliding stability of the slider 302.
[0026] As a technical optimization solution of the present utility model, the mounting structure 5 includes a slide rail 501, two slide rails 501 are fixedly connected to the mounting seat 204, and two slide grooves 502 are provided on the cutter 205, and the slide rails 501 are slidably connected to the inside of the slide grooves 502; the cross-section of the bottom end of the slide rail 501 is a trapezoidal structure, and the cross-section of the bottom end of the slide groove 502 is a trapezoidal structure; a stopper 503 is fixedly connected to the bottom end of the mounting seat 204, and the cutter 205 conflicts with the stopper 503; four bolts 504 are provided on the mounting seat 204, and the four bolts 504 are plugged into the slide rails 501, and four threaded holes 505 are provided on the cutter 205, and the bolts 504 are threadedly connected to the threaded holes 505, so that the cutter 205 can be quickly replaced through the mounting structure 5.
[0027] As a technical optimization solution of the present invention, a collection structure 4 is installed on the operating table 1, and the collection structure 4 includes two supporting plates 401. The bottom end of the operating table 1 is fixedly connected to two supporting plates 401 with an L-shaped cross-section, a baffle 402 is fixedly connected between the two supporting plates 401, and a collection frame 403 is provided between the two supporting plates 401; the bottom end of the collection frame 403 is fixedly connected to two mounting bars 404, and the mounting bars 404 are rotatably connected to two rollers 405, and the rollers 405 are rollingly connected to the supporting plates 401.

The scraps produced by cutting are collected by the collecting structure 4, which facilitates material recycling and improves energy utilization.
[0028] When the present invention is in use, when it is necessary to adjust the position of the guide bar 303 according to the width of the steel plate, the hand wheel 305 can be rotated according to the scale line 306. The rotation of the hand wheel 305 will drive the screw rod 301 to rotate. The rotation of the screw rod 301 will drive the two sliders 302 to slide toward or away from each other, thereby driving the two guide bars 303 to slide toward or away from each other. The distance between the two guide bars 303 is observed through the scale line 306 and adjusted to the width of the target hinge plate. The setting of the guide rod 304 improves the sliding stability of the slider 302. When cutting, the plate is placed under the guide bar 303 for guidance. On the base 202 at the bottom of the cutter 205, the hydraulic cylinder 203 is then started, the hydraulic cylinder 203 extends to drive the mounting seat 204 and the cutter 205 to descend, and the cutter 205 then shears the steel plate. After the steel plate is trimmed, when the steel plate is trimmed for the second time, the steel plate will push the scraps generated by the previous trimming into the collection frame 403 for collection. When the collection frame 403 is full, the limit block 407 can be rotated, the torsion spring 408 is compressed, and the limit block 407 no longer blocks the collection frame 403. At this time, the collection frame 403 can be pulled out from between the two support plates 401, and the mounting bar 40 The roller 405 on 4 rolls on the supporting plate 401, making it easier to extract the collection frame 403. After the collection frame 403 is extracted, the collection frame 403 can be lifted up by the handle 410 on the fixing ear 409, and then the empty collection frame 403 can be pushed between the two supporting plates 401. After the collection frame 403 contacts the baffle 402, the limit block 407 can be loosened, and the torsion spring 408 is reset, thereby driving the rotating shaft 406 and the limit block 407 to reset, thereby blocking the collection frame 403 and preventing the collection frame 403 from moving. When the cutter 205 needs to be replaced, the bracket 204 on the mounting base can be rotated. After the four bolts 504 are no longer connected to the four threaded holes 505 on the cutter 205, the cutter 205 can be slid to separate the slide rail 501 from the slide groove 502, and then the cutter 205 is disassembled. When the cutter 205 needs to be installed, the slide groove 502 on the cutter 205 can be aligned with the slide rail 501 on the mounting base 204, and then the cutter 205 can be inserted. When the cutter 205 block 503 hits, it means that the hole position on the mounting base 204 is aligned with the threaded hole 505 on the cutter 205. At this time, the bolts 504 can be installed to completely fix the cutter 205 to the mounting base 204.
